Organic Compounds An organic compound contains carbon and is a building block of living organisms. Carbohydrates Carbohydrates contain carbon, hydrogen, and oxygen. There is always twice as much hydrogen as oxygen. They are used by the body mostly for fuel. Examples: Sugars, starch, fiber Lipids Lipids are fats and oils. They also contain carbon, hydrogen, and oxygen. But the ratio of H to O is more than 2 to 1. Lipids are used to store energy in the body. They contain twice as much energy as carbohydrates. Lipids include fats such as butter and oils such as corn oil. Proteins Proteins contain carbon, hydrogen, oxygen, and nitrogen. Proteins are used to build body structures such as muscles and chemicals like hormones and enzymes. Proteins are made of long chains of units called amino acids. These chains are twisted and tangled. Examples of food containing proteins are meats, eggs, and fish. Nucleic Acids Nucleic acids contain carbon, hydrogen, oxygen, phosphorus. Nucleic acids are long ladder-like chains that coil. They are used to store and pass on genetic information. Examples are DNA and RNA. Carbon Atom Chemistry of Life
